Hikers can start at the major junction that is 3.7 miles east of Utah Route 313 along Gemini Bridges Road. The turn off for Four Arches is about 0.7 miles east of the junction and 0.8 miles west of Gemini Bridges.
The trail descends down into a grassy area and crosses a wash. There appears to be some private lodge and camp development in the level area down below, but I didn’t see any activity. There are some good views of the La Sal Mountains looming over some of the sandstone outcrops around the rim above the grassy areas. After crossing the grassy area, the trail heads up a canyon.
About 1.7 miles from the trail head, Bullwhip Arch and Mosquito Arch are visible on the right. From an angle in front and slightly to the left, the resemblance to a mosquito is laughably clear. Hike past the two arches a little and blue sky can be seen through both at the same time.
After visiting these arches, I realized that Bullwhip and Mosquito Arch are visible from near the trail head area, more than 1.5 miles away. Only one group of four ATVs passed me on a nearly perfect day. My hike to Gemini Bridges and the Four Arch Canyon was about 7.5 miles and took about 4:00 hours on a 55 F degree day. I drank 2 of the 3 liters of water I carried.
